“So what are you?” I ask the daughter of a Russian pop star (childhood in a gated community in Moscow, boarding school in Switzerland, and now college and clubbing off Sloane Square). “Where do you feel you belong to?” I ask two sisters, who went to boarding school near Cambridge, and whose father from Orienburg has bought them a boutique in Mayfair where they sell gem-studded Uggs. And they pause, think, and say: “We’re sort of in-ter-na-tio-nal.”
